How do we know that believers are with Christ after death?

The Bible teaches that for believers, death is not the end but the gateway to immediate fellowship with Christ. 2 Corinthians 5:8 states that to be absent from the body is to be present with the Lord. This means that upon death, the spirit of a believer goes directly to be with Christ, experiencing His fullness without delay. The assurance comes from Christ Himself, who said that those who believe in Him, even if they die, shall live again, emphasizing that faith in Christ secures eternal life and immediate entrance into His presence.
